I hope you all had a very Merry Christmas and a Happy New Year! I have a client who has a problem with their CLJ 1600. It has an issue with fading of the cyan and magenta colors. All toners are geniune HP replacements less than a month old. The black and yellow are fine as well as text. Purple tends to come out blue which makes sense if there is a cyan and magenta issue. Fuser is relatively new, and ETB looks good. I have attached a picture as well for your viewing pleasure!
I have seen some reference online about cleaning the mirrors but I have not heard of this process before. If anyone has any ideas, opinions, or suggestions, I am all ears! Thank you all in advance.
